New Delhi was the world’s most polluted capital for the third straight year in 2020, according to IQAir, a Swiss group that measures air quality levels based on the concentration of lung-damaging airborne particles known as PM2.5.
India was home to 35 of the world’s 50 most polluted cities, according to IQAir’s 2020 World Air Quality Report, which gathered data for 106 countries.
The findings were based on the country’s annual average of particulate matter PM2.5, airborne particles with less than 2.5 microns in diameter. Prolonged exposure to PM2.5 can lead to deadly diseases, including cancer and cardiac problems.
In 2020, New Delhi’s average annual concentration of PM2.5 in a cubic metre of air was 84.1, the study said, more than double the level of Beijing, which averaged 37.5 during the year, making it the 14th most polluted city in the world.

A study released by Swiss air-quality watchdog group IQAir on Tuesday found New Delhi, India, was the world’s most polluted capital city for the third year running, and South Asia overall had some of the worst air quality ever recorded.
Reuters dourly noted New Delhi’s particulate matter concentrations were “more than double the level of Beijing,” which is currently the 14th most polluted city on Earth. India’s pollution declined by 11 percent due to the coronavirus lockdowns, but it was still the third most-polluted country, right behind Bangladesh and Pakistan.
“Air pollution caused an estimated 54,000 premature deaths in New Delhi in 2020, according to a recent study by Greenpeace Southeast Asia Analysis and IQAir,” Reuters added.
